Ambush Bugs Patiently Waiting To Pounce

8-15-17 ambush bug 049A1961Ambush bugs, a type of assassin bug, are true bugs, in the order Hemiptera. (Although insects are often referred to as “bugs,” technically only insects in this order are classified as bugs by entomologists.) All true bugs have piercing and sucking mouthparts, and wings which are membranous and clear at the tips, but hardened at the base.

 Ambush bugs are usually brightly colored (yellow, red or orange) and have thickened front legs which are used to capture prey up to ten times their own size. They live up to their name, patiently lying in wait for unsuspecting prey, often in goldenrod flowers where they are very well camouflaged. An ambush bug, upon sighting an insect, suddenly seizes the prey in its powerful forelegs and quickly dispatches it with a stab from its sharp beak. It then injects digestive enzymes into its prey, after which it drinks the resulting liquid innards.


Trout-Lily’s Pollinators

5-7-14 trout lily pollinator IMG_1725Like Bloodroot and many other spring ephemerals, Trout-Lily (also known as Dog-tooth Violet and Adder’s Tongue) remains closed at night and on overcast days. On sunny days, bees are its main pollinators, but it is visited by many other insects, including Red-necked False Blister Beetles that feed on both its pollen and ovules.

When a bee visits a Trout-Lily flower, it usually removes half of the available pollen in one visit. In no apparent hurry, it often pauses in the middle of collecting to groom itself and pack pollen into the pollen baskets on its hind legs. It then heads directly back to its hive to unload the pollen. Unfortunately for the Trout Lily, this hampers cross-pollination, as it severely limits the amount of pollen that reaches other Trout Lily flowers. As compensation, Trout Lily has two sets of anthers – one set opens one day, the other opens the next, preventing a bee from collecting all the pollen from a given flower in one day, giving other insects the opportunity to cross-pollinate.
