The Squash Bee Smackdown

1
00:00:00,240 --> 00:00:05,640
Foreign welcome

2
00:00:06,140 --> 00:00:09,760
back to Secret Pollinators, the podcast that uncovers the hidden

3
00:00:10,260 --> 00:00:12,880
world of nature's most specialized matchmakers.

4
00:00:13,840 --> 00:00:17,600
I'm your host, Kelly from Montana, and today

5
00:00:17,920 --> 00:00:21,920
we're diving into one of the most dramatic pollinator rivalries in your

6
00:00:22,420 --> 00:00:23,120
backyard garden.

7
00:00:27,930 --> 00:00:31,370
Picture this. It's dawn in a summer garden.

8
00:00:31,850 --> 00:00:35,010
The squash blossoms are just beginning to open their

9
00:00:35,510 --> 00:00:39,290
golden petals, releasing their sweet, musky perfume

10
00:00:39,790 --> 00:00:43,490
into the morning air. But this isn't just any peaceful

11
00:00:43,990 --> 00:00:47,250
garden scene. This is ground zero for one

12
00:00:47,750 --> 00:00:51,530
of nature's most intense competitions. Welcome to

13
00:00:51,770 --> 00:00:53,770
the squash bee smackdown.

14
00:01:02,050 --> 00:01:06,130
Meet the competitors. In one corner, weighing in

15
00:01:06,630 --> 00:01:09,730
at about 0.12 of a gram,

16
00:01:10,690 --> 00:01:13,850
and at about half an inch long, we have

17
00:01:14,350 --> 00:01:18,610
the reigning champion of cucurbit pollination, the eastern

18
00:01:19,110 --> 00:01:22,540
squash bee. These fuzzy amber colored warriors have

19
00:01:23,040 --> 00:01:24,900
been perfecting their craft for millions of years.

20
00:01:26,660 --> 00:01:30,660
And in the other corner, we have the scrappy challengers, weighing in

21
00:01:31,160 --> 00:01:34,540
at about 0.16 of a gram and

22
00:01:35,040 --> 00:01:38,340
are also about a half an inch long, the European honeybees.

23
00:01:39,060 --> 00:01:42,380
Sure, they're not native and sure, they didn't evolve

24
00:01:42,880 --> 00:01:45,620
specifically for this job, but they've got numbers,

25
00:01:46,100 --> 00:01:49,460
organization, and a reputation for getting things done.

26
00:01:52,820 --> 00:01:54,900
But before we get into the main event,

27
00:01:56,100 --> 00:01:58,180
let me tell you why this matters.

28
00:01:59,780 --> 00:02:03,620
We're not just talking about bees here. We're talking about

29
00:02:04,120 --> 00:02:07,980
your pumpkin pie, your zucchini bread, your Halloween jack

30
00:02:08,480 --> 00:02:12,620
O lanterns. Every single squash, pumpkin gourd

31
00:02:13,120 --> 00:02:17,510
and cucumber in North America depends on this ancient dance between

32
00:02:18,150 --> 00:02:19,750
flower and pollinator.

33
00:02:22,630 --> 00:02:25,910
The backstory. An ancient partnership.

34
00:02:27,030 --> 00:02:30,270
Our story begins about 10,000 years ago, when the

35
00:02:30,770 --> 00:02:33,950
ancestors of squash were just wild boards growing

36
00:02:34,450 --> 00:02:37,910
in what's now Mexico. The squash bee was already there,

37
00:02:38,470 --> 00:02:42,000
waiting. Wait. While other bees were generalists,

38
00:02:42,160 --> 00:02:45,680
flitting from flower to flower like pollinator tourists,

39
00:02:46,320 --> 00:02:48,080
squash bees were specialists,

40
00:02:49,280 --> 00:02:52,080
the Navy seals of the pollination world.

41
00:02:56,720 --> 00:02:58,400
Here's what makes them so special.

42
00:02:59,600 --> 00:03:02,160
Squash bees are oligolectic.

43
00:03:02,560 --> 00:03:06,000
That's a fancy word meaning they put all their eggs in one basket.

44
00:03:06,760 --> 00:03:10,280
The cucurbit family. Their entire life

45
00:03:10,780 --> 00:03:14,520
cycle revolves around squash plants. The females emerge

46
00:03:15,020 --> 00:03:18,520
from underground burrows just as squash plants begin to bloom.

47
00:03:19,400 --> 00:03:23,080
They time their reproduction to match exactly when

48
00:03:23,580 --> 00:03:27,160
squash flowers are available. But here's where it

49
00:03:27,660 --> 00:03:31,720
gets really wild. Squash bees are early risers.

50
00:03:32,750 --> 00:03:34,590
We're talking 4am early.

51
00:03:35,550 --> 00:03:38,750
They're out there working on the flowers. Before sunrise,

52
00:03:39,230 --> 00:03:42,830
when the squash blossoms first open and are

53
00:03:43,330 --> 00:03:44,750
most receptive to pollination,

54
00:03:49,950 --> 00:03:54,110
the showdown begins. So picture a garden battlefield

55
00:03:54,610 --> 00:03:58,350
at dawn. The male squash bees have actually been sleeping inside

56
00:03:59,080 --> 00:04:03,160
the clothes squash blossoms all night. Talk about dedication

57
00:04:03,660 --> 00:04:07,560
to the job. As the flowers open, they emerge groggy

58
00:04:08,060 --> 00:04:11,240
but ready for action. The females arrive like clockwork,

59
00:04:11,400 --> 00:04:15,319
their specialized branched hairs perfectly designed

60
00:04:15,320 --> 00:04:19,400
to collect the large, sticky pollen grains. One female

61
00:04:19,900 --> 00:04:22,920
squash bee can visit dozens of flowers in a single morning.

62
00:04:23,640 --> 00:04:27,120
And here's the kicker. She's incredibly efficient.

63
00:04:27,920 --> 00:04:31,640
Studies show that a single visit from a squash bee can

64
00:04:32,140 --> 00:04:33,600
fully pollinate a female flower.

65
00:04:39,600 --> 00:04:43,400
But wait, here come the honeybees, fashionably late to

66
00:04:43,900 --> 00:04:47,440
the party. It's 8am and they're just waking up.

67
00:04:47,920 --> 00:04:50,640
The squash bees have been working for hours already.

68
00:04:51,590 --> 00:04:53,350
But the honeybees arrive in force,

69
00:04:54,870 --> 00:04:57,750
sometimes dozens to a single plant.

70
00:04:58,630 --> 00:05:01,350
Now, honeybees aren't bad at pollinating squash.

71
00:05:01,910 --> 00:05:05,510
They're just different. Think of it like

72
00:05:06,310 --> 00:05:08,950
if squash bees are surgical specialists,

73
00:05:09,590 --> 00:05:13,230
Honeybees are general practitioners. They'll visit the

74
00:05:13,730 --> 00:05:17,670
flowers, sure, but they're not perfectly adapted for the job.

75
00:05:20,890 --> 00:05:24,210
Scoring the competition. So who wins this

76
00:05:24,710 --> 00:05:27,530
smackdown? Well, it depends on how you keep score.

77
00:05:28,330 --> 00:05:32,490
If we're talking pure pollination effectiveness, squash bees

78
00:05:32,990 --> 00:05:37,090
dominate. Research from Cornell University found that squash

79
00:05:37,590 --> 00:05:41,530
bee visits result in significantly more seeds per fruit and larger fruits

80
00:05:42,030 --> 00:05:46,050
overall. One study showed that flowers visited only by squash

81
00:05:46,550 --> 00:05:50,130
bees result produce fruits with 20% more seeds than those

82
00:05:50,630 --> 00:05:54,570
visited only by honeybees. But honeybees have numbers

83
00:05:54,890 --> 00:05:57,970
in agricultural settings. Managed honeybee

84
00:05:58,470 --> 00:06:02,170
colonies can provide consistent pollination even when native bee

85
00:06:02,670 --> 00:06:05,890
populations are low. They're the backup dancers

86
00:06:06,390 --> 00:06:07,050
that keep the show going.

87
00:06:14,180 --> 00:06:17,460
Here's the plot twist, though. This isn't really a

88
00:06:17,960 --> 00:06:21,900
competition. In healthy ecosystems, squash bees

89
00:06:22,400 --> 00:06:26,020
and honeybees work different shifts and complement each other perfectly.

90
00:06:26,420 --> 00:06:30,660
The squash bees handle the early morning rush, when the flowers are most receptive.

91
00:06:31,140 --> 00:06:34,820
And the honeybees take the day shift, providing backup pollination

92
00:06:35,220 --> 00:06:37,620
and helping with late opening flowers.

93
00:06:41,170 --> 00:06:44,810
The secret life underground we can't talk about

94
00:06:45,310 --> 00:06:48,290
squash bees without mentioning their most remarkable feature,

95
00:06:48,530 --> 00:06:51,970
their lifestyle. While honeybees live in colonies,

96
00:06:52,450 --> 00:06:56,330
squash bees are mostly solitary. The females dig

97
00:06:56,830 --> 00:07:00,690
burrows up to two feet deep in the ground near squash plants.

98
00:07:01,330 --> 00:07:05,080
These aren't just simple holes. They're architectural

99
00:07:05,580 --> 00:07:07,000
marvels with multiple chambers.

100
00:07:13,480 --> 00:07:16,920
Each chamber contains a ball of pollen mixed with nectar,

101
00:07:17,320 --> 00:07:20,360
basically a protein bar for their larva.

102
00:07:20,920 --> 00:07:24,360
The female lays an egg on each ball, seals the chamber

103
00:07:24,860 --> 00:07:28,840
and repeats the process. When the larva hatch, they have

104
00:07:29,340 --> 00:07:33,740
everything they need to develop into the next generation of squash bee specialists.

105
00:07:35,100 --> 00:07:38,900
And the really amazing part, These bees spend most of

106
00:07:39,400 --> 00:07:42,620
their lives underground. The adults only

107
00:07:43,120 --> 00:07:45,980
live for about six to eight weeks during squash blooming season.

108
00:07:46,860 --> 00:07:50,540
The rest of the year, they exist as pupae

109
00:07:51,040 --> 00:07:54,460
or larva. In their underground chambers. Waiting for next

110
00:07:54,960 --> 00:08:02,280
year's Squash the

111
00:08:02,780 --> 00:08:06,280
Conservation Challenge here's where our story takes a

112
00:08:06,780 --> 00:08:10,800
serious turn. Squash bees, despite being incredibly specialized

113
00:08:11,300 --> 00:08:14,560
and effective, are facing challenges. Urbanization,

114
00:08:15,200 --> 00:08:18,520
pesticide use, and agricultural practices that

115
00:08:19,020 --> 00:08:22,160
eliminate wild spaces are reducing their populations.

116
00:08:22,960 --> 00:08:26,560
Unlike honeybees, which can be managed and moved around in

117
00:08:27,060 --> 00:08:30,990
hives, squash beet conservation depends on maintaining their underground

118
00:08:31,490 --> 00:08:35,350
nesting sites and reducing pesticide use during blooming periods.

119
00:08:36,790 --> 00:08:40,110
Many gardeners unknowingly destroy squash bee nests

120
00:08:40,610 --> 00:08:44,070
when they till soil near their squash plants. The good news?

121
00:08:44,710 --> 00:08:48,470
You can help these champions if you grow any plants in

122
00:08:48,970 --> 00:08:53,910
the cucurbit family squash, pumpkins, cucumbers, melons Leave

123
00:08:54,410 --> 00:08:58,190
some bare soil nearby for nesting sites. Avoid tilling within

124
00:08:58,690 --> 00:09:02,590
10ft of your squash plants. And if you see small bees visiting

125
00:09:03,090 --> 00:09:07,710
your squash blossoms at dawn, you know that you're witnessing millions

126
00:09:08,210 --> 00:09:10,710
of years of co evolution in action.

127
00:09:14,470 --> 00:09:16,950
Now, as usual, I want to hear from you.

128
00:09:17,910 --> 00:09:21,310
Have you spotted squash peas in your garden? I'd love

129
00:09:21,810 --> 00:09:24,860
to see your photos and hear your stories. Here's your mission,

130
00:09:25,330 --> 00:09:28,890
if you choose to accept it. Next time you're near squash

131
00:09:29,390 --> 00:09:32,570
plants in the morning, take a moment to observe. Can you

132
00:09:33,070 --> 00:09:36,330
spot the difference between the early rising squash bees and

133
00:09:36,830 --> 00:09:40,730
their later arriving honeybees? I want

134
00:09:41,230 --> 00:09:45,410
to hear about it. Post your photos with hashtag Secret Pollinators

135
00:09:45,570 --> 00:09:48,730
and tag me. And if you're

136
00:09:49,230 --> 00:09:51,960
growing squash this year or next year,

137
00:09:52,360 --> 00:09:56,360
consider leaving some bare soil nearby for our underground champions.

138
00:09:57,160 --> 00:10:00,960
Every nesting site helps. And speaking of

139
00:10:01,460 --> 00:10:05,280
helping, if you've enjoyed this episode, please consider leaving

140
00:10:05,780 --> 00:10:09,160
me a review on your podcast platform. It really helps

141
00:10:09,660 --> 00:10:13,080
other nature lovers find. Our show, and reviews help us reach

142
00:10:13,580 --> 00:10:16,440
more people who want to support these incredible pollinators.

143
00:10:20,890 --> 00:10:24,410
That's all for today's episode of Secret Pollinators.

144
00:10:25,290 --> 00:10:28,450
Next time, we're diving into the mysterious world

145
00:10:28,950 --> 00:10:32,889
of the night shift moths, the goth cousins

146
00:10:33,389 --> 00:10:35,610
of butterflies, but with better work ethic.

147
00:10:36,570 --> 00:10:40,490
Until then, keep your eyes open for the secret Pollinators everywhere.

148
00:10:41,450 --> 00:10:44,930
They're out there working quietly to keep our

149
00:10:45,430 --> 00:10:49,010
world blooming. I'm Kelly from Montana and this

150
00:10:49,510 --> 00:10:53,130
has been Secret Pollinators podcast. Thank you for being

151
00:10:53,630 --> 00:10:55,970
part of my community and pollinator champions.
